Detecting School Violence Using Artificial Intelligence to Interpret Surveillance Video Sequences

Abstract

In this study, we present a skeleton-based approach for detecting aggressive activity. The approach does not require much powerful hardware but is very fast in realization. There are two stages in our method: feature extraction from video frames to evaluate a person’s posture, and then action classification using a neural network to determine if the frames contain bullying scenes. We also selected 13 classes for identifying aggressor’s and victim’s behavior, created a dataset of 400 min of video data that contains actions of one person and 20 h of video data containing actions of physical bullying and aggression. The approach was tested on the assembled dataset. Results show more than 97% accuracy in determining aggressive behavior in video sequences.
